UNITED 'wimir aur. H. Ross, on JERSEY my, nnw'anitsnxfi Application filed November-18 was. Seria1-No. 149,()38.

The device of my invention relates to ventilators and refers particularly to ventil a-tin'g deflectorsfor window use.

One of the objects of my invention is a 5 ventilator which the deflector element is readily attached to, and removed from the supporting side pieces V Another object of my invention is a ventilator free fromno-i-se. and rattle'incident to in air impact. I

Another object of my invention is a ventilator made of inexpensive material.

Another object of my invention is a knock-down ventilator Whiclrcan be easily )5- assembl-ed and easily set up.

The above and other valuable features of the device of my invention will be evident upon a consideration of the attached drawings and my explanation thereof.

In the accompanying drawings illustrating modified forms of the device of my in vention, similar parts are designated by similar numerals.

Figure 1 is a front view of the device of my invention in window frame placement. Figure 2 is a cross-section through the line 22 of Figure 1. v

Figure 3 is an enlarged cross-section through the. line 3-3 of Figured.

Figure 4 is a perspective View of the end support of my device. I v

Figure 5 is a fragmentary side'view of the deflector.

Ell

Figure 6'is a fragmentary vertical crosssection of a modified form of deflector.

v The particular form of the device of my invention shown in Figures 1 to 5 inclusive comprises a deflector 10 made of corrugated 1 cardboard having'a protective edging of 41) paper, or textile material, 11 attached to and covering its upper edge.

My device, as lllustrated, has two end sup= shape, number,arrangementfor material of ports each having a window'casement element 12 and an angularly positioned deflector. support 13, each deflector support 13 having a plurality of bent over cut-out fasteners 14, 14. Each casing element 12 has a plurality of openings 15,15 forpurposesde- 'scribedlater. 7

It is evident from the. above that the device of my invention comprises a 'cardboardf deflector and two metallic end supports. The end supports may beinthe form of a flat blank, scored to allow of the angular positioning of the elements 12 and 13 with deflector supports.

This-deflector support 13 of; each-end port is bent at right anglestothe casement element 12 and each fastener 14 is bent at right angles to its deflector support 13. The two end supports are then attached to the two window easements 16,16'by means of nails, or screws, passed'through the openings 15, 15. The fasteners 14, 14 are then I passed throughcorresponding openings 17,

17 in the deflector 10 and bent down to abut 2 upon the further face of the defiector, as shown particularly in Figure 3.

The deflector 10. may be attached. to the end supports12, '12 before the latter is at-' tached to-the casement if desired 7 The modified form of my device shown in Figure 6 is similar to that described, except that a metallic rod 18 is positioned deflector 10 in order to increase itsrigidity. In order toremove the deflector 10,.the

fasteners 14, '14 are straightened andthe deflector withdrawn.

It" will thus be seen that ing and shipping properties, is readily as upon and held upon the upper edge of the f p my device is economic in cost, possesses valuable pack I sembled and readily attached, thatthe de! flector may, be readily removed and. that, because of the fact that thereis no metal-to;

metal contact, it is free from rattle and noise 1 due to irregular wind impacts.
